To all whom it may conce n Be it known that l, LINN B. Asno'rr, n-

citizen er the United States, residing- Bridgeport, in the county of Fairrleld and the State of Connecticut, have invented a new and useful insulator, of which the following is a specification.

My invention relates 'o insulators for use with pull so or the like, in which flexible metallic cord or chain is used as on actuating and the objects of my improvement or to provide means of guarding the operet against occidental shock by eii'ectuslly insulating the operating chnin from the'other parts of the mechanism. to pro-- ride insulation which csnbe n sorted with great facility. Third, to provide an easy means of lengthening or ing a broken chain; Which operation is tremely difficult to one not equipped for this Work.

lNith these and other objects in View, which will be readily apparent to those skilled in the art, my invention consists or the novel construction, combination and u'iore fully rsngement parts heroine: described, il List-rated and clan l i' hile susceptible to embo-chhe rious Ways by the use of different mechanical equivalents, 1 y invention is Well exemplified by the single form thereof shown in the accompanying drawings, in which:

Figure I is on external View of an electrical pull socket embodying the present invention. Figs. H and Hi are longitudinal sections or" my novel insulator. Fig. IV is a sidei'iew or a terminal beiore being embedded in toe insulating material. Fig. V is a projection of. Fig. IV showing the edge View of this terminal and Fig. V1 is e. projection of Fig. V showing the top View of the some. confining my description to the preferred form shown in the drawing, but Without thereby limiting my invention, 1 is a pull socket for electric lights, of any ordinary construction, 2 is the operating chain composed oi": a series of metallic beads or bolls, flexibly joinedtogether, and such as is com,- monly used in connection with such socket. 3 is my novel insulator as inserted in said chain.

Referring to Figs. ll and is the body of my insulator composed of'any inand 5 are spring tersulating material. 0

minals made from any spring metal, and which are molded or similarly confined partly Within-the assuming material, and ore spaced apart .to prevent electrical conduction.

Referring to Figs. IV, V and VI, the spring terminals are made preferably iron. 2t single piece of metal folded back upoi itself as 6, in which position it tends .0 remain. are provided 'h hole 7 the sides, which hole is adopted to a ball of he chain. .Zinother oylcu J med in the end of e spring as 8, which openingallo-Ws space 101' the cord or link wh ch connects the bulls of the tlmin. 1' opening flares outwardly toward iliis lutie the end. as at 9, which allows ball )f the chain to be inserted with ease and WliCll in no Way interferes with the retaining action of the spring after the ball is in place. These spring terminals are preferably pan tiully molded which forms the body of the insuhuor and are somewhat enlarged toward the end as shown at 10 to insure their retention therein. To insert the insulator, a ball of the chain is pressed against the flaring end 7f the spring terminal. This separates the two parts of the spring and allows the bill to enter the opening 7, after which the spring returns to its former condition and holdsthe bell securely against retraction.-

Having thus described my inventiomwhat I claim as new is:

1. In an insulator for 2. conductor, the combination of two metal elements, the outer ends of each of said elements havii 1g yieldingly separable parts for engaging an end'of the conductor between said parts, the inner ends of each of said elements oeing spaced apart from each other, and in suluting material enveloping and embedding said inner ends for insulating from each other and mechanically securing said. elements.

2. In an insulator for a conductor. the combination 0i Jiro metal elements, the outer ends of each of said elements having two yieldingly separable spring blades for receiving and removably clamping between them an end of the conductor, the inner ends of each or" said elements being spaced apart from each other, and insulating material enveloping and embedding said inner ends for insulating from each other and into the insulating material mechanically securing said elements, the each of said elements being spaced apart spring blades of said elements extending from each other, and insulating material- Within said insulating material. enveloping and embedding said inner ends 3.
